Yaah, I know, it’s way too late (and nobody cares) but for those who are interested:
Here is the transcription of the beautiful ED of kannagi.
And the best thing is: It plays pretty well on the piano.
Piano sheet: Musuhi no toki.pdf
Mp3: midi + mp3
Btw: I initially wanted to transcribe the full ED but, yeah, it was too much work and I’m too lazy now.
I’ll post the full version later. (seriously this time)
